作者：XueQin Wang,Xu Xing,FengJu Zhang,Kong Xin

摘要：This work presents a reference system overview to improve the efficiency of biological improvement of saline-alkali soil developed during the last thirty years,ranging from connotation,general methods and species,soil desalination,soil structure,soil organic content,microbial flora,enzyme activity,yield and economic benefits.The reference system presented is divided into three main groups:suitable varieties,suitable cultivation measures,and a comprehensive evaluation system.There has been a lot of research on biological improvement of saline alkali soil,but these studies are very fragmented and lack a comprehensive standard system.Also,there is a lack of practical significance,particularly with regard to optimal species,densities and times of sowing for particular regions.On the other hand,the corresponding cultivation measure is very important.Therefore,a reference system plays an important role to the effect of biological improvement of saline alkali soil.
